I have designed enclosure for SB17NRXC35-8 and SB25STC-C000-4 it is ML-TL 1.25/2.5 with 120cm length, and tuned approximately to 36Hz, but does not have knowledge how to design crossover, so could someone design crossover for me. The enclosure is from factory data not measured

I can show you some crossover options for the original, but discontinued SB25, not the SB25STCN that you want to use. Still, it may help with the woofer section of the crossover. You won't be able to directly use the tweeter crossover, but it may give you some help with doing your own.

Looks like I posted right after Jerome. The point about the tweeter, though, is important. I'm not sure that a direct replacement would work, at least not optimally.

Why do you ask for help ?

SB Acoustics 2-Way Title Page

That page has 4 different designs to choose from, I'd probably go with one of those, they look pretty straightforward.

Crossovers I have a little problem with them not sufficient knowledge (most important),no measuring equipment for frd etc…

Comparing the manufacturer data sheets for the suggested tweeter and the old one I used, there will be some difference in response with the same crossover. The new, smaller SB has a higher Fs with a different raw highpass response, so it will have some difference around the crossover area. I can't vouch for how well it will suit. It may be close enough, but the only way to be sure would be to test.

Thanks for link it seems my quest is ended

The job has been done in the right way, nothing to do more.

But if you read the article, he gives the PCD file. You can do your own crossover.
